My inventionrelates to that class of apparatus which is employed forchanging temperatures of fluids for Various purposes, and an. object ofmy invention, amongothers, is the product ionlof apparatus of thissortfwhich is simple in con"- struction and particularly eflicient inthe results obtained by its use. I v

One form of a deviceembodying my invention and in the construction anduse of which the objects herein set out,`as well as others,y may beattained is .illustrated in the accompanying drawing, in which Figure 1is a side view of a radiator unit embodying my invention.

Figure 2 is an end view of the same.

Figure 3 is a view in section on a plane denoted by the dotted line 3-3of Fig. 1.

Figure 4 is an edge View.

Figure 5 is a view in section on a plane denoted by the dotted line 5-5of Fig. l.

Figure 6 is an isometric View of a fragment of the unit with partsbroken away to show construction.

Figure 7 is a detail view on enlarged scale of'a portion of one of theradiating plates.

Figure 8 is a view similar to Fig. 6 but illustrating a'modied form ofthe invention.

As hereinbefore mentioned my improved aplparatus is for the purpose ofchanging temperatures by means of fluids Vcirculating through tubes, insome instances the apparatus being employed to lower the temperatures offluids circulating through such tubes and in other instances thetemperatures of fluids owing through the tubes being radiated to lowertemperatures outside of the tubes.

A unit comprising a portion of such an apparatus and embodyingmyinvention includes a series of radiating plates all of which plates aregenerally of the same construction,` each plate 9 preferably being ofconsiderable widthA as compared with its length and having notches I0formed in one edge and preferably evenly spaced from one another.` Aflange I I vextends around the border of each notch,'these anges beingformed by bending the material outwardly substantially at right anglesto the plane of the plate to form the notches and as clearly shown inFig. 7 of the drawing. These anges may each be unbroken, but I prefer toform them in sections, in the structure shown each flange comprisingthree pieces, but it willbe understood that 'my invention is not limitedin this respect but may consist of any desired number of pieces.

The notches I0 are formed to receive a conducting tube or tubes I2 whichvpreferablyare bent to provide parallel lengths separated at distancesequal to the distances between the notches IB so that a tube so bentmaybe placed in .the

notches in the plates, and as shown in Figs. land 5' 2 'of the drawing.'The ends I3 of the-1tube are extended for the purpose ofconnectiontosources of fluid and for the discharge of suchuid whic iscirculated through the tubes.

" The flanges Ii are 'for the purpose of properly l0 spacing theconducting plates so that the intervals between the plates will besubstantially the same throughout the unit, the flanges .on each plateresting yagainst the surface of the adjoining plate and thereby avoidingany necessity l5 Y for special means for properly spacing the plates,

the anges serving this purpose. As a `means for maintaining uniformspacing ofthe plates between the tubes and the opposite edges of theplates spacers I 4 lare stamped out 20 'from the plate and bent at anangle thereto and y as shown in Fig. 3 of the drawing. These spacers aretapered from a narrow dimension atlthe Vsurface of the plate to a widerdimension at the outer end of the spacer. When the spacers are thus 5bent into spacing position it will be noted that the wide outer end ofeach spacer is located opposite the narrow end of the opening in theadjacent plate so that there is no dangerof the spacer entering saidopening and the plates are thus 30 properly spaced.

As a means for defiecting currents of air flowing through the unitbetween the radiating plates curved ribs I5 extend lengthwise of theplates between the two rows of spacers I4 and as shown in Fig. 3 of thedrawing. These ribs are'curved crosswise of the plates, and as clearlyshown in Fig. 7, and in additionto the function of deflecting currentsof air these ribs alsoserve toy stiffen the plates and thereby provide avery rigid 40 structure. Each unit is 'provided at opposite sides withholding plates I6 having flanges II similar to the flanges IIhereinbefore described, the flanges I'I encountering the curved portionsof the tubes 45 serving to position the set of radiating platesand'thereby to secure such plates in place upon the tubes.v Brackets I8are formed at the ends of the holding plates for the purpose ofsecuringv the unit as a whole in place for use. 50 The structure shownin Fig. 8 is substantially the same as that hereinbefore described withthe exception that the radiating plates I 9 are extended as at 20 beyondthe tube I2, Yas shown in Fig. 8, but as in the case of the apparatusrst described the tubev when bent is inserted in place in the unit fromone edgeV thereof, being placed in the notches 2l and then slid intoposition. Any suitable means for securing the tube within the notches inthe radiating platesmay be employed as desired.

In accordance with the provisions of the patent statutes I havedescribed the principles of operation of my invention, together with thedevice which I now consider to represent the best I embodiment thereof;but I desire to haveit un' A derstood that the device shown is onlyillustrative and that the inventiongmay be carried out by uses otherthan those Y 4.
